Commit eaf4fac47807 ("net: stmmac: Do not accept invalid MTU values")
started using the TX FIFO size to verify what counts as a valid MTU
request for the stmmac driver. This is unset for the ipq806x variant.
Looking at older patches for this it seems the RX + TXs buffers can be
up to 8k, so set appropriately.
(I sent this as an RFC patch in June last year, but received no replies.
I've been running with this on my hardware (a MikroTik RB3011) since
then with larger MTUs to support both the internal qca8k switch and
VLANs with no problems. Without the patch it's impossible to set the
larger MTU required to support this.)

If the imp-controlled PHYs feature is enabled, driver can not
call phy driver interface to set loopback anymore and needs
to send command to firmware to start phy loopback.
Driver reuses the existing firmware command 0x0315 to start
phy loopback, just add a setting bit in this command. As this
command is not only for serdes loopback anymore, rename this
command to "xxx_COMMON_LOOPBACK", and modify function name,
macro name and logs related to it.

When the imp-controlled PHYs feature is enabled, driver will not

When the imp-controlled PHYs feature is enabled, phydev is NULL.
In this case, the autoneg is always off when user uses ethtool -a
command to get pause parameters because hclge_get_pauseparam()
uses phydev to check whether device is TP port. To fit this new
feature, use media type to check whether device is TP port.
And when user set pause parameters, these parameters need to
always set to mac, no matter whether autoneg is off.

It appears that each DMA channel has its own interrupt and both rings
can be configured (the same way) to handle interrupts.
1. Make ring interrupts code generic (make it operate on given ring)
2. Move napi to ring (so each has its own)
3. Make IRQ handler generic (match ring against received IRQ number)
4. Add (optional) support for TX interrupt

Spectrum-2 and later ASICs support sampling of packets by mirroring to
the CPU with probability. There are several advantages compared to the
legacy dedicated sampling mechanism:
* Extra metadata per-packet: Egress port, egress traffic class, traffic
class occupancy and end-to-end latency
* Ability to sample packets on egress / per-flow
Convert Spectrum-2 and later ASICs to perform sampling by mirroring to
the CPU with probability.
Subsequent patches will add support for egress / per-flow sampling and
expose the extra metadata.

Sampling of ingress packets is supported using a dedicated sampling
mechanism on all Spectrum ASICs. However, Spectrum-2 and later ASICs
support more sophisticated sampling by mirroring packets to the CPU.
As a preparation for more advanced sampling configurations, split the trap
configuration used for sampled packets between Spectrum-1 and later ASICs.
This is needed since packets that are mirrored to the CPU are trapped
via a different trap identifier compared to packets that are sampled
using the dedicated sampling mechanism.

support mirroring with probability, where every 1 in N matched packets
is mirrored.
Extend the API that creates the binding between the trigger and the SPAN
agent with a probability rate parameter, which is an attribute of the
trigger. Set it to '1' to maintain existing behavior.

When packets are mirrored to the CPU, the trap identifier with which the
packets are trapped is determined according to the session identifier of
the SPAN agent performing the mirroring. Packets that are trapped for
the same logical reason (e.g., buffer drops) should use the same session
identifier.
Currently, a single session is implicitly supported (identifier 0) and
is used for packets that are mirrored to the CPU due to buffer drops
(e.g., early drop).
Subsequent patches are going to mirror packets to the CPU due to
sampling, which will require a different session identifier.
Prepare for that by making the session identifier an attribute of the
SPAN agent.

The alternative implementation of this function in a header file
is declared as a global symbol, and gets added to every .c file
that includes it, which leads to a link error:
arm-linux-gnueabi-ld: drivers/net/ethernet/mellanox/mlx5/core/en_rx.o: in function `mlx5e_tc_tun_update_header_ipv6':
en_rx.c:(.text+0x0): multiple definition of `mlx5e_tc_tun_update_header_ipv6'; drivers/net/ethernet/mellanox/mlx5/core/en_main.o:en_main.c:(.text+0x0): first defined here
Mark it 'static inline' like the other functions here.

To avoid false lock dependency warning set the ct_entries_ht lock
class different than the lock class of the ht being used when deleting
last flow from a group and then deleting a group, we get into del_sw_flow_group()
which call rhashtable_destroy on fg->ftes_hash which will take ht->mutex but
it's different than the ht->mutex here.

MLX5_INTERFACE_STATE_UP is far from being reliable check for success to
recover, because it can be changed any time and health logic doesn't
have any locks to protect from it.
The locks are not needed here because health recover is good to have,
but not must to success, so rely on the returned value from the
mlx5_recover_device() as a marker for success/failure.

The check of MLX5_INTERFACE_STATE_UP is completely useless, because
the FW tracer cleanup is called on every change of the interface
and it ensures that notifier is disabled together with canceling
all the pending works.

The FW tracer check is called twice, so delete one of them.
